Lidar-derived Beach Morphology (Dune Crest, Dune Toe, and Shoreline) for U.S. Sandy Coastlines
These data include dune crest, dune toe, shoreline, beach width and beach slope morphology for U.S. sandy coastlines derived from lidar.
Features
- Data range from 1998 to near present
About
These datasets define the location and elevation of the dune crest, dune toe, and shoreline at 10-meter intervals alongshore for dozens of processed lidar elevation surveys. Beach width and beach slope are calculated from the dune toe to the shoreline and are also included at each shoreline location.
Beach morphology data like these support vulnerability assessments for many places along the nation’s coastline that are subject to extreme storms and long-term shoreline change. These assessments require elevation data across diverse geographic regions and covering a time span of many years.
Product of the USGS National Assessment of Coastal Change Hazards (NACCH) project.
